中文摘要：

利用区域地质、构造、遥感地貌、地球物理、野外露头等多方面的证据,标定出龙门山断裂带横断层。在分析卧龙—怀远、虎牙断裂南段和白龙江等横断层特征及分布的基础上,探讨了横断层的控震作用。研究认为,龙门山断裂带横断层具有独立发震、使龙门山主断裂带分段活动及分段发震、与主逆冲断裂联合发震、在主震发生后控制余震传播和引发余震等多种方式的控震作用。

英文摘要：

Combining with the overall evidence of regional geology, tectonic, remote sensing landscape, geophysics and field outcrop investigating etc. , we identified the transverse faults in Longmenshan fault zone. Basing on analyzing the distribution and characteristics of transverse fault, such as Wolong-Huaiyuan Fault and southern segment of Huya Fault and Bailongjiang etc. , we discussed the earthquake-controlling function of the transverse fault. The research results show that the transverse faults in Longmenshan Faults Zone has the earthquake -controlling function, such as causing earthquake independently, making the different segment of Longmenshan main faults active and triggering earthquakes separately, occurring earthquakes join with the main thrust faults, controlling the spread of aftershock after the main earthquake and triggering aftershocks etc..
